WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 759,228, dated May 10, 1904.

Application filed November 14, 1903. Serial No- 18l.178- (N0 model.)

To all, whom it may concern:

Be it known that I, FRANK V. BARTLETT, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Water-I-Ieaters, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to water-heaters, and has for its object the obtaining of a construction which is compact, efiicient in its action,

. and simple to manufacture.

It is afurther object to avoid danger of clogging in water circulation by forming a construction in which the water-passages are free from obstructions or shoulders against which sediment might lodge.

With these objects in view the invention consists in the construction as hereinafter set forth.

In the drawings, Figure 1 is a sectional elevation of my heater. Fig. 2 is a perspective view of a portion of the heater with the outer casing removed. Fig. 3 is a perspective View of the supporting and spacing thimbles for the heater. Fig. i is a section through the heater. Fig. 5 is a section on line m a, Fig. 1.

A is a cylindrical casing of any suitable construction, but preferably with outer and inner metallic walls a and b, separated by a lining c, of any non-conducting material, such as asbestos. Within this casing is arranged a series of heatensections B. Each of these secthe segments are oppositely inclined so as to form a wedge-shaped cross-section which is large at the center and tapers toward the periphery, and the opposite sides thereof converge inwardly. Such a construction provides-an unobstructed passage-way from the 'center to the edge of the chamber within the section, and the inclined bottoms will tend to prevent the accumulation of sediment.

A series of sections B are superposed and are connected to each other preferably by threaded nipples g, which engage with threaded apertures in the hub c. The adjacent sections are arranged with the segments, one opposite the wedge-shaped openings and the other so as to compel the circulation of the heated products of combustion in a zigzag course through the casing A. The top section is connected to a conduit C, preferably extending vertically, and on this conduit is sleeved a cap D, which connects at its periphery with the casing A. Beneath the lowest section is arranged theheater E. This is preferably of annular form and is supported upon the pipe F, which forms an inlet connection to the lowest section B. Air-passages are provided both at the center and at the periphery of this heater, and to this end the central aperture it is formed of greater diameter than the pipe F, while the diameter of the heater is less than that of the casing A. The heater is secured upon the pipe F by means of a spacing-spider G, arranged between the lowest section and the upper face of the heater, and asecond spider H is clamped upon the pipeFbelow the heater and engages with an annular seat vi therein.

1 is the air-mixing tube, which extends laterally from the heater, being provided with the usual adjustable mixer j and gas-controlling valve The npper face of the heater E is provided with a series of radially-extending grooves Z, between which are the ridges m, having the jet-apertures a therein.

At the base of the casing A is a supportingring J, which has inwardly-extending lugs 0, resting upon the heater E.

The cap I) is apertured at p and may be connected with the pipe K for carrying away the products of combustion.

A heater constructed as described is exceedingly simple to manufacture, as the sections B may be formed by casting and may be quickly connected and assembled in relation to each other. It is to be observed that the water-passage through the heater is unobstructed from the bottom to top and that each of the disks has unobstructed connection with the central passage. Moreover, the heating of the segments will cause a constant current of water in and out through the central opening, which in connection with the inclined walls will prevent the lodging of sediment.

It will be understood that all the heated products from the burner E will pass into contact with the segments of the superposed sections, and not only the bottom faces of said segments are heated, but also the upper walls, by reason of the zigzag course through which the products are compelled to pass. The construction is rendered compact by reason of the fact that the sections B extend completely across the casing and in contact with the walls thereof.

What I claim as my invention is 1. A water-heater comprising a series of sections each comprising a pair of oppositelydisposed hollow sector-shaped disks centrally connected at their inner ends by unobstructed passages, and arranged out of line with the adjacent disks and a casing inclosing said sections.

2. A water-heater comprising a series of sections each comprising a pair of oppositelydisposed hollow sector-shaped disks having an uninterrupted connection with one another at their inner ends, and having inclined top and bottom walls forming within a wedgeshaped chamber inclined toward the center, and having unobstructed communication with the central passage through the series of sections. 7

3. A water-heater comprising a series of superposed sections each comprising a sectorshaped disk, said disks being centrally connected to each other, and forming an axially-- unobstructed passage through the series, a tight-fitting cylindrical casing surrounding said sections, an inlet-water conduit connected centrally to the lowest section, and a burner secured upon said conduit, and supporting said casing.

4:. A water-heater comprising a series of superposed sections each consisting of oppositely-arranged hollow sector-shaped disks connected by a hollow central hub, said sections being arranged axially and connected to each other so as to arrange the disks of one section opposite the intermediate spaces in the adjacent sections, a cylindrical casing fitting around the series of sections, an inlet-conduit connecting axially to the lowest section, an annular burner surrounding said inlet-conduit, spaclng-splders for clamping said burner upon said inlet-conduit, so as to form a central air-inlet passage, and an annular air-passage between the periphery of the burner and the casing, and means for supporting said casing upon said burner.

5. A water-heater comprising a series of hollow-disk sections of sector shape, centrally connected to each other at their inner ends and having inclined top and bottom walls forming within a wedge-shape chamber with the widest vertical portion nearest the disk center, producing unobstructed communication with the central passage through the series of sections.

6. A water-heater comprising a series of superposed sections each comprising a hollow disk segment, said segments being centrally connected to each other, and forming an axially-unobstructed passage through the series, a tight-fitting cylindrical casing surrounding said sections, an annular burner at the lower end of the casing, and an annular supportingring comprising a vertical portion engaging the lower outer surface of the casing and an inwardly-extending flange engaging respectively the lower edge of the casing and the upper surface'of the burner.

7 A water-heater comprising a casing, a heating medium therefor, an unobstructed conduit for conveying the water centrally through said casing, and a hollow sector-shaped disk communicating at its innermost portion with said conduit, by an unobstructed passage-way.

8. A water-heater comprising a casing, a

heating medium for the interior thereof, an unobstructed conduit for conveying water centrally through said casing, and ahollow sectorshaped disk communicating with said conduit, the top and bottom walls of said disk converging outwardly and the opposite sides thereof converging inwardly.

9. A water-heater comprising a casing, a heating medium therefor, a water-conduit therein, and a series of superposed sections each comprising a plurality of oppositely-disposed hollow sector-shaped disks, the top and bottom walls of said disks inclining inwardly and the opposite walls thereof converging inwardly to a point adjacent said conduit, said disks communicating with the conduit at their innermost portions, and the adjacent series being arranged out of line.

In testimony whereof I aflix my signature in presence of two witnesses.

FRANK V. BARTLETT.
